Brand recognition at such a young age

Today Lillian was on my lap while I was in front of my computer. She was looking intently at the keyboard (I have a windows machine), then she pointed to the bottom left key and said “Windows”. I then asked did someone tell her that, she said no, so asked James and he said no, so it has to just be down to the picture. I find this amazing as Julia and Lillian both have recognised the Apple brand, as it is quite easy for them having an apple on everything. Now Lillian is saying windows and yes she was right it was windows. It is probably not that amazing as it is obvious from the pictures, although I am just taken back on the brand recognition at such a young age. Gosh help this household when they are more aware of what the brands are.
